First off let me thank you for your hard work and diligence in creating this tool! Well done.
I have been testing your application on our FSK405 servers for the past week. I like DankRider have been using Fragomatic's rcon tool for the past umpteen years, so that is the closest thing I have for a comparison. As they seem to do many of the same things your tool is better laid out and is by far easier to teach Rcon to newer users. Not to mention as far as I can tell, Fragomatic is not developing his tool anymore. It is what it is. That being said your tool has a huge upside. I do have some suggestions if you are willing to lend an ear.
Suggestion:
I have not been able to figure out how to add commands to the Auto-complete without manually editing your RconCmd.db, which BTW works well. Is there a way you can create a method to allow easy additions to this db? Maybe under the Menu → Tools → Auto-Complete list.
Additional commands that are used on FSK servers listed below:
g_allowvote
g_gear
g_hotpotato
g_knockback
g_password
g_respawndelay
g_respawnprotection
g_waverespawns
g_redwave
g_bluewave
Suggestion 2:
I have a visual impairment/issue with black/white. Would you consider making it where the user can select alternative background and text colors within the console? This is would be a nice feature request for a future release.
Once again, I am excited to see people put forth the effort to keep UrT alive. You have made it easy for us older guys to teach server administration to the newer folks. Keep up the great work and if you ever need to find Dank or Me we are always in our TS2 (Soon moving to TS3) at:
TS2 Server Address: fsk405.com
ps. I also use the features that Dank spoke about in his previous posts but didn't want to beat that horse... Auto-Status-Refresh and Poor-mans Server log...etc.
